What is JPEG2000?
JPEG2000 AV over IP technology provides a robust solution for transmitting high-quality video and audio over IP networks. Utilizing the JPEG2000 compression standard, it offers visually lossless compression, ensuring that the original image quality is preserved while significantly reducing bandwidth requirements. This technology is ideal for applications where high-resolution video, such as 4K content, needs to be transmitted across long distances with minimal latency. The benefits of JPEG2000 AV over IP include efficient bandwidth usage, low latency, and support for high-quality video walls, multi-viewer setups, and broadcast applications, offering a flexible and scalable solution for modern AV systems.
JPEG2000 FAQ
Q What is JPEG2000 AV over IP?
JPEG 2000 AV over IP is a method of transmitting high-quality audio and video signals over IP networks using the JPEG 2000 codec for video compression. It ensures visually lossless video quality while minimizing latency, making it ideal for most professional AV applications.
​
Q How does JPEG2000 work for AV over IP?
JPEG 2000 AV over IP uses encoders, network switches, and decoders to deliver high-quality AV signals. Encoders compress video from sources like cameras or PCs using the JPEG 2000 codec, creating visually lossless data streams. These streams are packetized and sent over a managed Ethernet switch, which efficiently routes the packets to their destinations while ensuring minimal latency and smooth performance. Decoders at the destination reconstruct the data into high-quality video and audio, synchronized for playback.
​
Q What are the benefits of JPEG2000 for AV over IP?
-
High-Quality Video: Visually lossless compression ensures excellent image fidelity.
-
Low Latency: Suitable for real-time applications with 1-2 frame latency like live events and presentations.
-
Scalability: Unrestricted expansion by simply adding extra end points.
-
Network Efficiency: Compressed streams optimize bandwidth use while retaining quality, all within a 1Gb pipe.
​
Q What applications are suited for JPEG2000 AV over IP?
JPEG 2000 is ideal for video walls, digital signage, training rooms, education facilities, and other high-resolution collaborative environments. It’s combination of low bandwidth requirement and low latency make it a good general choice for most AV over IP applications.
Q What are the network requirements?
A 1Gbps network is sufficient for JPEG 2000 AV over IP applications, most modern switches feature the settings required to run AV over IP like jumbo frames.
​
Q How does it compare to other AV over IP codecs?
JPEG 2000 provides superior video quality at lower latency compared to highly compressed codecs like H.265. However, it requires more bandwidth, making it suitable for applications where quality takes precedence over network efficiency. For uncompromising AV over IP video performance and even lower latency, SDVoE using 10Gb networks would be a better option.
​
Q Can JPEG2000 integrate with existing systems?
Yes, JPEG 2000 AV over IP systems are compatible with standard network equipment and can be integrated into existing AV infrastructures. Placing AV over IP onto an existing network is called a converged network.
